cPanel is a Linux-based web hosting control panel that provides a graphical interface and automation tools designed to simplify the process of hosting a web site. cPanel utilizes a 3 tier structure that provides capabilities for administrators, resellers, and end-user website owners to control the various aspects of website and server administration through a standard web browser.

In addition to the GUI, cPanel also has command line and API-based access that allows third party software vendors, web hosting organizations, and developers to automate standard system administration processes.[2]

cPanel is designed to function either as a dedicated server or virtual private server. The latest cPanel version supports installation on CentOS, Red Hat Enterprise Linux (RHEL), and CloudLinux OS.[3] cPanel 11.30 is the last major version to support FreeBSD.

Application-based support includes Apache, PHP, MySQL, PostgreSQL, Perl, and BIND (DNS). Email based support includes POP3, IMAP, and SMTP services. cPanel is accessed via https on port 2083.

Once installed, cPanel cannot be easily removed. cPanel’s FAQ states that the best way to uninstall cPanel is by reformatting the server. However, uninstall guides are available online for expert server administrators who do not wish to reformat their server. Similarly, it should only be installed on a freshly installed operating system with minimal prior configuration.

Hardware requirement for servers vary widely, depending on the server’s purpose and its software.

Since servers are usually accessed over a network, many run unattended, without a computer monitor, or input device, audio hardware and USB interfaces. Many servers do not have a graphical user interface (GUI). They are configured and managed remotely. Remote management include MMC, SSH or a web browser.

Large servers

Large traditional single servers would need to be run for long periods without interruption. Availability would have to be very high, making hardware reliability and durability extremely important. Mission-critical enterprise servers would be very fault tolerant and use specialized hardware with low failure rates in order to maximize uptime. Uninterruptible power supplies might be incorporated to insure against power failure. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory,[8] along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, allowing technicians to replace them on the running server without shutting it down, and to guard against overheating, servers might have more powerful fans or use water cooling. They will often be able to be configured, powered up and down or rebooted remotely, using out-of-band management, typically based on IPMI. Server casings are usually flat and wide, and designed to be rack-mounted.

These types of servers are often housed in dedicated server centers. These will normally have very stable power and Internet and increased security. Noise is also less of a concern, but power consumption and heat output can be a serious issue. Server rooms are equipped with air conditioning devices.

Bitcoin[note 5][note 6] is a digital asset[16] and a payment system invented by Satoshi Nakamoto,[note 7] who published the invention in 2008[12] and released it as open-source software in 2009.[18] The system is peer-to-peer; users can transact directly without an intermediary.[19]:4 Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain.[20] The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency.[1] Bitcoin is often called the first cryptocurrency,[21][22][23] although prior systems existed.[note 8] Bitcoin is more correctly described as the first decentralized digital currency.[19][26] It is the largest of its kind in terms of total market value.[27]

Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins.[19] Besides being obtained by mining, bitcoins can be exchanged for other currencies,[28] products, and services.[29] Users can send and receive bitcoins for an optional transaction fee.[30]

Bitcoin as a form of payment for products and services has grown,[29] and merchants have an incentive to accept it because fees are lower than the 2–3% typically imposed by credit card processors.[31] Unlike credit cards, any fees are paid by the purchaser, not the vendor. The European Banking Authority[32] and other sources[19]:11 have warned that bitcoin users are not protected by refund rights or chargebacks. Despite a large increase in the number of merchants accepting bitcoin, the cryptocurrency does not have much momentum in retail transactions.[33]

The use of bitcoin by criminals has attracted the attention of financial regulators,[34] legislative bodies,[35] law enforcement,[36] and media.[37] Criminal activities are primarily centered around black markets and theft, though officials in countries such as the United States also recognize that bitcoin can provide legitimate financial services.[38]

Bitcoin has drawn the support of a few politicians, notably U.S. Senator Rand Paul, who accepts donations in bitcoin.[39]

What is Litecoin :

Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
